### Is your feature request related to a problem or challenge? In https://github.com/apache/datafusion/pull/16954 we are only going to support inner joins because of complexities with other join types. This would benefit cases such as: ```sql COPY (SELECT 1 AS c1) TO 't1.parquet'; COPY (SELECT 1 AS c1, 2 AS c2) TO 't2.parquet'; CREATE EXTERNAL TABLE t1 ( c1 INT NOT NULL ) STORED AS PARQUET LOCATION 't1.parquet'; CREATE EXTERNAL TABLE t2 ( c1 INT NOT NULL, c2 INT NOT NULL ) STORED AS PARQUET LOCATION 't2.parquet'; select * from t1 left join t2 using (c1) order by t2.c2 limit 100; ``` ### Describe the solution you'd like An implementation similar to that of the logical optimizer that accounts for the edge cases and allows some filters to be pushed down. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
